This section of the NavMesh content example shows how a Pawn can navigate through a set of obstacles. You can try adding and moving more blocks around to make more complicated paths. The navigation system will often list things as "simple" because it is not taking in much external data, like if an Actor is walking on ice or through tar, but can quite handily navigate in three dimensions, accounting for bridges and overhangs along the way, to any desired location.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.
